The box has one mighty special feature: it will charge a user's smartphone while they eat. The company has partnered with a Mumbai-based digital agency, Blink Digital, to make the "Watt a Box" concept a reality. In terms of specs, the box features a built-in 6100 mAh power bank, and two USB-ports with the ability to charge Android smartphones and iPhones. KFC has launched a contest on its Facebook page, giving users a chance to win the box. You can watch the "Watt a Box" promo video here on YouTube.
